How this service works
Cron parser. Parses any 5 / 6 / 7-field cron expression or @yearly / @monthly / @weekly / @daily / @hourly macro and returns a plain-English explanation, frequency bucket, validation flag, and runs-per-day estimate. Same backend as cron-explain under a clearer slug.
Output
Returns a plain-English description of what the cron schedule does, a frequency bucket (e.g. daily, weekly, hourly), a boolean validation flag indicating whether the expression is valid, and a numeric estimate of how many times per day the job would run.
Example use cases
Example prompt
“Can you tell me what the cron expression '0 9 * * 1-5' means in plain English, whether it's valid, how many times a day it runs, and what frequency bucket it falls into?”

Endpoint
POSThttps://x402-deployer.x402-deployer.workers.dev/cron-parseWhen to prefer
Use this endpoint when an agent needs to explain, validate, or estimate the frequency of a cron expression in a human-readable format, especially when working with CI/CD pipelines, task schedulers, or DevOps automation where non-technical users need to understand job schedules.
Side effects
- Invalid or malformed cron expression returns validation flag false with error detail
- Unsupported field count (not 5, 6, or 7 fields) may return a parse error
- Unrecognized macro string returns validation error
- Network or worker timeout returns 5xx error
